The term "chipped" references the installation of an aftermarket electronic chip that provides alternate air/fuel maps in order to obtain different levels of performance.

the term chipping and ecu is the process of removing the factory eprom from the board. and replacing it with a pre programmed eprom that instantly gives you More hp and more tq. raised rev limiter and optimized vtec engagment we generally charge 150 to chip your ecu and ship it back to.

Mugen/skunk2/clones = That crap is a hackjob on the OEM code, stuff that has no place being removed has been removed from those chips, they are tuned to some setup and you have no idea what that setup is to mimic it, and they cause problems down the road.

Ask Rob aka GSRswapandslow what a warmed over GSR program did for his OBD1 converted ITR swap on the dyno. Start with the base Honda code, and modify as needed, after the particular setup's needs.

With how chipping is easy to get into these days, you might strongly consider doing it yourself if you can't find anyone local to give you a personalized tuning service on a wideband.

well sorry to hear you had a bad experience... but to say a programed ecu doesnt work is a false statement.. it works great for us check the sigg. that was on oem ecu with our ecu programmed chip.. no stand alone.. chipped ecu =

I wasn't criticising OEM ECU tuning, I represent ECU tuning. I was criticising 1) blind "chipping" services that don't suit a custom setup and 2) the Mugen/Skank/Feels/Spoon clones that all disable vital ECU diagnostic routines *for no reason whatsoever* which leaves the recipient SOL when down the road something goes wrong with their VTEC solenoid/oil pressure or one of the sensors in the distributor, etc.

My CRX is about as fast as the one in your sig, except I have no clue about proper suspension setup and drive like a little girl - 60' foot times somewhere around 3 seconds is the picture I'm trying to paint. It's running a specifically tuned for my setup OBD0 PR4, and a little boost.

HUH??? like i said, you must have gotten a bad batch or something.. give it another chance.. i bet it will work for you.. ok now as far as your car and mine are concerned. I think your sadly mistaken.. first off. you dont know what it even runs so that theory basically goes right out the window... and 3 sec 60 foot times??? HUH?? if your pulling 3 secs in the 60 foot. you are not even in the same galaxy as my street car.. nice try though.. good luck ..

bottom line.. chipped ecu works great.. and dont let anyone tell you differnt..

I will have to agree!!!!! I chip ecu's, and I've sold over 120+ chipped p28's here on h-t alone (check vouch thread) and yes I do visit the pgmfi forums to learn A LOT of useful information. Personally, I gained about 25 whp through out the power ban, and 10 lb's of torque overall while I dynoed my gsr w/ the stock ecu, versus my chipped p28 ecu all motor program *which was based off of the skunk2 maps. My qtr mile times dropped as well with the chipped ecu. People have their methods and own ways to go about the chipped ecu issue, so basically do whatever you like that makes you happy, but consider everyone's review's, thoughts, and opinions first.

I did all the original beta testing for Ghettodyne and for Uberdata, stunna. I get invited to pgmfi.org's founder's birthday parties and such. I cannot stress enough how much blind "chipping" sucks - here is a good example of that. Again, I advocate tuned ECU packages and not using crap codebases what have half your ECU diagnostics gutted.

I hang next to cars with 120 mph traps from a roll. I'd say that's a fair indication of the power to weight involved - comparable to your drag queen.

I just got done tuning a car for a kid.

97 teg w/ JDM ITR, skunk2 stage 1 cams + valvetrain, standard bolt ons.

Was running a genuine bona-fide Skunk2 ECU and a VAFC whacked to hell.

Left running a chip I made custom with Uberdata 1.66, 4 hours of street tuning / wideband time and a lot of guesswork.

First thing out of Ben's mouth when he drove his car around block: "Is this my car? What did you do to it?"

Point being: tuning makes all the difference.

Also, I'd highly recommend not playing stupid kid games with J. Davis. Aside from being altogether too smart for his own good, he is the king of the trailerpark warriors. It is pure folly to underestimate the ingenuity bred from poverty.

I think you guys confuse who and what I am, and where I am coming from:



These are Techedge 2.0 widebands, a big step up from the DIY-WB 1.0 I cut my teeth on. Yes, I own two of them, one is a dedicated in-car unit for my CRX, the other is the one I use to tune other people's cars with. A wideband is crucial in nailing an AFR down... if a generic cookie cutter chip gets you close, I (or any one of the several dozen tuner boy franchises on HT) can get you much closer. You'll note the OBD1 pass thru harness I constructed, my OBD0 unit is still installed in my CRX.



As I stated above, I make harnesses. I prefer not to, but I do take on special requests. RLZ ENGINEering went from a heavy **** 99 Si as their NA car to a 92 DX hatchcrap, and needed a harness made so they could still run their OBD2B AEM EMS, and pronto. Bingo, call Joey.



This is how tune on the fly engine management is done in the trailerpark, with a little help from PGMFI. Pictured is an RTP (Real Time Programmable) ECU and misc pieces... it is not entirely finished as I have a daughterboard I am building to be able to convert from OBD1 to OBD2 compliant IAB control with the flip of a switch.

Oh, yeah, it's a P05 ECU. Don't let anyone tell you that the 72 hp Civic CX ECU can't control VTEC or IABs.



Once I get the tune nailed by wideband on my RTP setup, I burn the final tune to conventional 27C256 chip and install in the recipient's ECU. Stunnas might not know this, but Honda ECUs aren't compatible with anything slower than 170ns memory.



I use Batronix Eprommer 3.2 or 3.3 to burn my final tunes... yes, yes, I have two chip burners too. In the trailerpark, we do nothing by half measure.

Oh, yeah, the bins above the burners have enough small parts for 400 OBD1 VTEC conversions. The small caps in the center are the 22 pF units used on the 1720 motherboards.



A little less than "fitty" SK5151... these are the high powered switching transistors used to activate VTEC. They run about $5/per retail, in small quantities, and if you look closely these are new units... nothing against old ones pulled from ECUs, but you run out of those quick.



My current ECU collection, I'm getting a little low At an average value of $100/per I could buy a decent daily driver you wouldn't feel embarrassed to take a girl out on a date in.



My tubular stainless turbo manifold and Holset HX35. Full-Race would sell you a variant of that manifold for about $1200 shipped. The turbo flows around 60 lbs of air... yup, 550 whp.

Nope, I don't know anything about 11 second cars, just because I suck at launching a car that has twice to three times the torque at 4000 rpms than any NA Honda does at any given point.

I feel I've done very well for poor trailertrash... above all I most certainly possess the reading comprehension to understand the differences between tuning and chipping, why disabling half your CEL codes is bad m'kay, and abilities/setups/experience far outstripping those who are criticising me as an ignorant fool (okay, okay, I still drive like a little girl... you got me there).

BTW...



My kid is way ******* cute. She rules

Worst $150 bucks spent EVAR. You are no better than those $50 superchargers on ebay, but at least those would probably give more of a gain

replacing the EPROM is all it is, contains the essential maps for ign timing and fuel along with other things like VTEC engagement, rev limiter, etc.

We do it usually for $150 shipped back to you and I require a full list of the mods you have, things like header, intake manifold, compression, injector size, fuel pressure, camshafts, valvetrain, cat/testpipe are the things I usually ask from my customers before doin an eprom for them.

We've had great results, check out my site's dyno section I think I have a dyno of before and after EPROM reprogramming: http://www.gbrtuning.com

J. Davis is an exceptionally intelligant person. I honestly do not understand why he posts on this board tailored to idiots.

I am an EE and ME formally educated. I do not feel i have any knowledge or skill or experience advantages over J. Davis.

When you guys argue with him, the results remind me of a time i put soda-crackers in the sand blaster.

ROFLMAO!!!!!!!!!

LMAO ill smoke the crap out of your whatever you have.. dont even try and step.. lol froma roll he said!!! LMAO hey come to a drag event and ask the officials if you can setup the lights just for you so you can start off with a wussy *** roll start!! LOL id pay money to see that!! he said next to cars that trap 120.. lol dude you have no idea. and you are clueless when it comes to drag racing.. so just quit it now.. stick to birthday parties and your crazy ecus with no check lights or whatever.. if i when off on a rolling start my traps would not be 120 anymore tough guy.. it be much higher! but im sure my STREET CAR WILL DUST you right from the start till the end of the 1/4..
